' Specification of Letters Patent.

Application filed July 18,1908. Serial No. 826,764.

To all whom it may concern:

Be it known that I, HENRY F. BEoHMAN, of Battle Creek, in the county of Calhoun and State of Michigan, have invented certain new and useful Improvements in Machines or Castin -Boies for Making Stereotype-Plates and I ereby declare that the followin is fa re ings, whichform part of this speci cation.

This invention is an improved machine or.

casting-box for making stereotype plates. for use on rotary cylinder printing presses, and the object of the invention is to make the drag or matrix holdin portion of the box, movable from a vertica l horizontal position, so that whi e in the latter position the matrix can be readily placed in or removed therefrom,'and the stereotype plates can be readily removed; the drag is so be practically balmoved to either pomeans whereby the movement of the drag to and from thecope causes it to automatically assume the proper positions; and also provide" means whereby be securely locked'to the cope during the casting operations, and can be released and partly started away from the cope after .thecasting operations are completed.

The invention will be fully understood anced, and can be easily from thefollowing description and the accompanying drawings, in which-- F'gure 1 is a plan view of the box closed, but showing the drag open indotted lines. Fig. 2 is a side elevation of Fig. 1. Fig. 3 is a rear elevation of Fi" 2. Figs. 4-. and '5 are details of the drag iaste'ning devices; and Figs. 6 and 7 are detail leasing devices. Fig. 8 is a detail view 0 the shaft.

Upon a suitable base 1.is mounted the cope 2, preferably in a vertical position, said cope being convex on its inner or castingface,.as usual, so as to give the deslred contour to the inner side of the stereotype plates.

gether the space'therebetween will form a mold for a curved Attached to verse bars 2 said'barsiprojecting into the path of the side edges of of the latter toward the co e at the exact ask 3, so as to stop the movement mathematical point. The rag is provided with the usual hinged side guides 3" on its edges by which an ordinary matrix M can be held n position during the casting operation.

The drag 3 is provided With side-trunnions 3 on which are rollers.3 which are ada ted to run upon ways 1 on the upper en s of side frames 1' attached to base 1, so that the drag can be readily moved toward and from the fixedcope 2. The drag may be provided with handles 3 to facilitate its movement by the operator. The ways 1 may be upturned at their rear ends 1 ing ofl the'ways by momentum. The drag is also provided with arms or brackets 3 having rollers 3 on their outer ends, which rollers engage guide-slots 1 in the side frames 1*, he main portion of said slots being vertical, but their upper-ends are bent horizontal Pl 1 inward toward the cope as at 1".

econstruction of the parts is such that whenthe drag is moved inward toward the cope rollers 3 and slots 1 cause the drag to i assume a vertical position by the time roller 3 reaches the part 1? aralleLwith the cope, atter; and on the outas it closes against the drag it first separates Ward movement of the then is tilted over. to a horizontal 'positionfas indicated in dotted lines Figs- 1 and 2 and remains in such osition while the stereotype platjis remove and the matrices arranged. he trunnions are so located that the drag is practically pivotally' balanced thereon, so that very little eflort is-required to move the drag in or out, and it is automatically tilted to vertical or horizontal position by the arms 3 and slots 1 In order to fasten the drag securely against the 'cope during the casting o erations, the is rovided, adjacent t e trunnions,

tov prevent the drag rollof slot 1, then the drag is kept perpendicular,

dralg wit stu s 3', which are adapted to be enfrom the cope, and a gaged by hooks 4 hung loosely on an eccentrically journaled rock-shaft 4,hav1ng eccentric journal portions 4 by which it is supported in'bearings 2 attached to the rear or outer side of'cope 2.

On the shaft adjacent the hooks are fixed collars 4 to which are attached pins 4 that are adaptedto engage -arc shaped slots 4 in the end ofthe hub of the adjacent hook (see Figs. 4 and 5) so that the shaft can be rocked somewhat without affecting the hooks 4 Thus the shaft 4 can be partly turned by hand-lever 4 startinglfrom the position shown .in Fig. 4, before t e hook4 will be aflected but after pin 4 reaches the rear end 1 of slot 4 the further backward movement of lever 4 to the position shown in F1 5, will,

'- the'shaft as a means for initiallg through pin 4, cause hook 4 to isengage' stud 3 This rocking lay of the shaft, independently of the hoo s, enables me to use separating the dra from the cops, whic is accomplished y friction rollers, or cams 4 on the shaft adjacent the hooks; and when the shaft is rocked by moving lever 4 to throw the hooks into engagement with the studs 3 the rollers 4 will move away from, or clear of, the adjacentedges of the drag; (see Fi 6) but as the lever 4 is moved ackwar the rollers or cams 4 are swung inward toward and into contactwith the rear edges of the dra at each side of the cope, and after the hoo s 4 disengagestuds 3 said rollers 4, on the continued rearward movement of lever 4 en age the edges of the drag and-force it away om and clear of the cope (see'F1g. 7) unlocking the box and enabling the operator to readily move the dra out to the position shown in dotted lines in ig; 2.1,, 4

Owing to the eccentric mounting-of the shaft 4, after the hooks are closed a further downward and rearward pull on lever '-4 causes the hooks to draw the drag solidly and forcibly against the cope, and seal the flask tightly during the castin operations the slots 4 being lon enoug to permit this movement before t e pins 4 reach the ends of the slots. The hooks 4 drop onto pins 3 by gravity as lever 4 is swung rearward. It will be seen that by reason of the balanced construction or mounting of the drag practically n0,exertion is required to move the drag from horizontal to vertical position; that the arms 3 and slots 1 effectively prevent the drag striking the cope while bein tilted, or moved to or from the cope; an

that the provision for a slight direct separat- I 'ing movement'of the drag to and from the copein finally closing or initially opening the box insures an accurate fittin of the matrix in the mold, and the proper c earance of the cast plate from the grooves-in the cope.

Having described my invention What I I claim as new and desire to secure by Letters Patent is:

1. In a stereotype castin -box, the combination of a fixed cope, side rames beside the cope having horizontal ways on their upper ends, L-shaped guide-slots having their horizontal portions substantially parallel with the ways and extendin toward the cope, a swinging1 drag provide with wheeled trunnions w ereby it is supported on said guideways, and arms attached to the dra and engaging said slots whereby the drag is turned as it is moved on the ways, substantially as described.

2. In combination, a cope, and a drag movable to and from the cope; with an eccentric ally mounted rock-shaft beside the cope, hook-arms loosely hung on said rock-shaft and adapted to engage the drag to lock the latter to the cope; collars on said shaft beside the hooks, and pin-and-slot-connections between the collars and hooks whereby the shaft is permitted a certain extent of movement without turning the hooks, substantially as'described.

3. In a stereotype casting-box, the combination of a cope, a drag, a rock-shaft, hooks .hung on said shaft adapted to engage and lock the dra to the cope, and eccentrics on said shaft ailapted to force the drag away from the cope after the locking devices have released the drag, substantially as described. 4. In a stereotype casting-box, the combination of a cope, a drag, an eccentrically mounted rock-shaft attached to the cope, hooks hun on said shaft adapted to engage studs on t e drag to lock the drag to the cope, and eccentric on said shaft ada ted to move the drag away from the co e a 'ter the locking devices have disengage the drag, substantially as described.

5. In astereotype casting-box, the combination of a cope, a frame havin horizontal ways and inverted L-shaped guide-slots below the ways having their horizontal portions substantially parallel with the ways and extending toward the cope, a drag havin wheeled trunnions supportin it u on said ways, and arms provided with rol ers connected to the drag, and engaging the guide-slots. 6.
